Sounds like your green panel is out of alignment. Has the TV been moved or jarred recently?

Generally speaking rear-projection panel alignments need to be done internally by professionals. Check for a local TV technician that specializes in projection TVs.

Ws-65611 color shadows


You need to turn down the voltage on all 3 crt's. You have a red one, a blue one and a green one. Slowly adjust the knob down until you don't see the shadow any more. Then adjust your color in the user menu.

After having our tv in storage for aver a year, now it has a green shadow to it. What could be wrong/


Not sure I understand what you mean by green shadow. I would check the fluid in the green and blue CRTS and verify they are clear. I would do this if the green color seemed fuzzy or blotchy looking on the screen.

When looking on a blank screen, do you see any arc lines of either green, blue or red? If so, you would need to lower the screen voltage for that particular CRT.

Mitsubishi TV Model #WS65903 - Green Shadow Lines on Screen


Something is not right here--The green is adjustable in the TECH menu--did this person adjust or try to adjust in the customer or the TECH menu?

If you confirm actual model number I can tell you how to get into the TECH menu--yes--green will not adjust in customer menu--it determines geometry and is only adjusted in the TECH menu.

Also, this set requires any convergence adjustments to be done in 480 and then in 1080--if only adjusted in one mode the other will still be bad.

Let me know if you know how to adjust in TECH menu or not--with exact model number I can tell you how to get there.

If this helps you rate this solution as I do this here for free.

Green shadow on white objects Mitsubishi WS - 55857 The right edge of white objects have a green shadow that gets larger as the camera pans away. I've adjusted convergence and turned off...


Its been a long time since I did it, but I believe you can adjust the green convergence grid by using the service menu. I found instructions on doing this over on the avsforum message board (years ago) so you might want to search there.

Green shadows surrounding bright whites


finally a consumer that gives us plenty of info :)
sounds like an overdriven green tube, the only thing you can try is to find the G2/Focus block assembly, either behind front speaker grill or remove back of set and look for a black box approximately 5"X5" , this box will have 6 philips type adjustment screws(plastic) 3 are for focus, do NOT adjust these,
the other 3 are marked "screen" the center screen adjustment screw is for green, turn it VERY slowly counterclockwise while the set is running and pray that your problem dis-appears, be advised that this is a HIGH VOLTAGE device so one hand in your back pocket the other hand turns the screwdriver, if the problem does not go away you have a poor green tube, good luck, sorry I can`t give you the exact location of the G2/Focus block, manufacturers move them to different places every year.
